Checking for Print Filtering

Check for print filtering by using the lpstat -o command.

$ lpstat -o luna
luna-10           fred         1261   Mar 12 17:34 being filtered
luna-11           iggy         1261   Mar 12 17:36 on terra
luna-12           jack         1261   Mar 12 17:39 on terra
$

See if the first waiting request is being filtered. If the output looks like the above example, the file is being filtered; the printer is not hung, it just is taking a while to process the request.
